I have a website where I sell shareware. There is a freeware version (light version) of the software, and there is a full version which must be purchased. I have a website statistic, but the statistic you get from the server logfiles is not very good and gives only small informations about your customers. What I want is a PHP application for a complete user statistic of the website. I need to know: a) where does the website visitor come from? (Did he click on a banner or a link, and if yes, on which) b) did the user download the freeware light version of the software? If yes, when (date,time etc.). Only successfull downloads must be counted, not broken downloads! Also I want the time which the user needed for downloading the freeware light version. c) did the user buy the full version? (date,time etc.), did he download the full software after he paid with creditcard, and how long did it take for him to download the full software? d) statistic about how long usually a user needs between visiting the website (also how many times), downloading the freeware light version and buying the full version etc. e) on the frontpage of the system is the statistic over the whole tim period and the statistic of the most referer websites/banners, also statistic from where the most visitors came, from where the most visitors came which downloaded the freeware light version, and finally from where the most visitors came which purchased the full version, also there must be a searchmask for searching by date,day,week,month,year etc. Please bid only if you have experience with high-performance PHP/MySQL applications because the whole statistic record must be very fast and consume small server ressources, the website gets thousands of hits daily. Please NO forum posts, I want real bids, not useless comments.
